8 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

8.1 Application Information

The device will typically be used to compare a single signal to a reference or two signals against each other.

Many users take advantage of the open drain output to drive the comparison logic output to a logic voltage level

to an MCU or logic device. The wide supply range and high voltage capability makes this comaprator optimal for

level shifting to a higher or lower voltage.
